bergamottin, a major furanocoumarin in grapefruit juice, can be used to increase bioavailabilty of some compounds.
Grapefruit seed extract has high anti-oxidant properties.
I took this from pureliquidgold site.
Grapefruit seed extract is being used successfully in humans and animals alike to fight many types of internal and external infections caused from parasites (single and multi-celled), viruses, bacteria, fungus and more!
The greatest benefit is due to it's multipurpose (broad spectrum) effect. It is effective even if the causes of the infections are known, unknown or misdiagnosed. Grapefruit seed extract naturally detoxifies, enhances and supports the immune system.
Grapefruit seed extract contains high levels of vitamin C and E, and bioflavonoids. The important substances have an antioxidant action and can neutralize free radicals that damage cells and cause a number of illnesses.
Another important benefit of grapefruit seed extract is that it is helpful in alkalizing the blood. Alkalizing the body fluids (raising pH) is one of the single most important health regeneration benefits available as disease causing microforms (fungi, bacteria, virus etc.) cannot survive in an alkaline oxygenated environment. Though lemons, limes, and grapefruits are chemically acid, tests show that when they are metabolized in the body they actually have an alkalizing effect. They have very little sugar and they contain an abundance of oxygen. This is a plus for anyone fighting candida or any other disease. Conclusion: Eat more fresh vegetables and less processed foods as most all vegetables are alkaline forming in the body.
Grapefruit seed extract is effective at very low concentrations. During 1989-90, an international research team (reported in the Journal of Orthomolecular Medicine, Volume 5, No. 3, USA, 1990) examined the effects of GSE and compared this with 30 effective antibiotics and 18 proven fungicides. GSE was found to perform as well as any and all of the tested agents. Without the harsh side effects. It is a natural alternative to strong antibiotics.
Grapefruit seed extract is nontoxic. According to an independent laboratory testing "Acute Oral Toxicity", it would take at least 4,000 times the normal dose of gse to produce a 50% chance of poisoning (called LD50).
Because grapefruit seed extract does not exhibit the harsh side effects and high cost of pharmaceuticals it is becoming the alternative health choice for naturopathic physicians, clinics and the general public.

Physicians have observed that the herpes simplex virus becomes inactive just ten minutes after the application of grapefruit seed extract.
So I don't see the seed extract to have the same effects as bergamottin.. but I also have another little tidbit of info for you, about this beneficial extract..
It increases the shelf life of injectable oils... tremendously. It has amazing preservative qualities. 2% of the total volume, and you're golden.
